Elder Cronos suggests you consult Fairy Mimyu concerning the raising of Hatchling to Strider.

Fairy Mimyu examines your hatchling and tells you the story of the four fairy trees and their guardians. She tells you to feed the sap of these trees to your hatchling. Go to each of the four fairy trees of wind, star, twilight and abyss and let your hatchling drink their sap. You must guard your hatchling as it drinks. When it has finished drinking, attach a fairy leaf to the fairy tree.

Your hatchling has drunk the sap of all four fairy trees-- the wind, star, twilight and abyss. The preparations for its growth have been completed. Return to Fairy Mimyu.
